Digital Radiography

Digital
radiography is a form of X-ray imaging, where digital X-ray sensors are
used instead of traditional photographic film. Advantages include time
efficiency through bypassing chemical processing and the ability to
digitally transfer and enhance images. Also less radiation can be used
to produce an image of similar contrast to conventional radiography.
Instead of X-ray film, digital radiography uses a digital image capture
device. This gives advantages of immediate image preview and
availability; elimination of costly film processing steps, a wider
dynamic range, which makes it more forgiving for over- and
under-exposure, reduction of expossure as well as the ability to apply
special image processing techniques that enhance overall display of the
image.
